String handling functions

In C, string handling functions are available in the <string.h> header file. These functions provide various operations to manipulate and work with strings efficiently. Here are some commonly used string handling functions in C:

strlen(): Calculates the length of a string (excluding the null terminator '\0').

strcpy(): Copies one string to another.

strcat(): Concatenates (appends) one string to another.

strcmp(): Compares two strings. It returns an integer value:

0 if the strings are equal

A positive value if the first character that doesn't match has a greater ASCII value in the first string

A negative value if the first character that doesn't match has a greater ASCII value in the second string

strchr(): Searches for a character in a string and returns a pointer to its first occurrence.

strstr(): Searches for a substring in a string and returns a pointer to its first occurrence.

These are just a few of the many string handling functions available in C. They can be very useful for various string manipulation tasks in C programming.
